Programmable Power for RF Amplifiers from Lambda
Genesys(TM) AC/DC 1U and 2U rack-mount power supplies give flexible,
reliable power in space-saving 1U and 2U packages. These supplies
offer outputs to 600 VDC and 400 A. Worldwide inputs, Active PFC, and
RS-232/485 interfaces are standard. Full set of user-friendly control
features. New option IEMD controls up to 31 slaves over RS-485 instead
of GPIB Card in each supply. New Advanced Parallel function allows up
to four to act as one for power up to 13.2 kW.

There's Always Room For One More
The microwave industry can safely be called a "mature" industry, with
many businesses exceeding 50-year lifetimes. This magazine itself will
be celebrating its 45th year of operation. In all that time, one might
think that the number of competitors in a given part of the microwave
marketplace would diminish or at least remain stable. But in this
newsletter, for example, several new companies (Keragis Corp. and
PrecisionWave Corp.) have announced offerings in their respective
parts of the industry, broadband amplifiers and test equipment.
This industry has grown and matured because of this entrepreneurial
spirit and the willingness of clever engineers with good ideas to take
a chance on a new business. Sometimes they have invested with their
own funds, sometimes with help from a bank or investors, but the risk
of starting a company is always great. And the industry has always
shown that it can support good products and good ideas, no matter how
many suppliers were competing previously in that space. For a good
microwave engineer, there's always room for one more company.

Precision Wave Builds Cellular Signal Generator
PrecisionWave Corp. entered the RF test market with their model p1211B
RF signal generator for cellular testing. With 1-Hz frequency
resolution from 800 to 1000 MHz and 1700 to 2200 MHz, the generator
can settle within 100 Hz of a new frequency in 1 ms when operating in
command list mode. The generator provides output levels from -100 to
+20 dBm with 0.1-dB resolution. The accurate, low-noise source (phase
noise of just -115 dBc/Hz offset 100 kHz from the carrier) provides
high modulation accuracy for a variety of cellular standards,
including GSM, EDGE, MACS, PHS, and WCDMA.

Keragis Offers Solid-State TWTA Replacement
Keragis Corporation has designed a patent-pending solid-state,
high-power traveling-wave-tube (TWT) replacement module capable of
providing 35 W output power from 6 to 18 GHz. Weighing a mere 0.5 lb.,
the model KHPA-0618-35W amplifier module features 20-dB typical gain
while drawing 11 A current from an +8-VDC supply. The design employs
numerous monolithic microwave integrated circuits (MMICs) and discrete
devices to minimize single-point failures. The reliable,
patent-pending design approach eliminates the "zipper effect" by which
failures of one device in some amplifiers can cause the failure of all
devices.

NoiseWave Launches Instrument Noise Generator
Noise specialist NoiseWave has announced the availability of its
NW3G-MINoise Instrument with broadband frequency coverage from 10 MHz
to 3 GHz. It delivers 0 dBm output power with output flatness of +/-
2.5 dB. It is available in a half-rack enclosure or in a tabletop
version and is ideally suited for wireless component and system
testing, bit-error-rate (BER) testing, signal simulation, and
cable-television (CATV) testing. Other output levels and frequency
ranges are also available.

HFET Hits 0.3-dB NF At 12 GHz
California Eastern Laboratories has introduced a heterojunction
field-effect transistor (HFET) that helps eliminate noise and improve
sensitivity in microwave receivers. Ideal for X-band and Ku-band
applications, the model NE3511S02 transistor achieves a noise figure
of 0.3 dB at 12 GHz with associated gain of 13.5 dB (running from a 10
mA, 2-V supply). The transistor is housed in a lead-free, plastic
surface-mount package measuring just 3.2 x 3.2 mm with recessed leads.

BAW Duplexers Filter Cellular Phones
EPCOS has begun volume shipments of its B7633 series
bulk-acoustic-wave (BAW) duplexers to a leading domestic US
manufacturer of mobile telephones. The BAW duplexers provide the
power-handling capabilities of ceramic filters with the small size of
surface-acoustic-wave (SAW) filters. They measure 5 x 5 mm with a
height of 1.35 mm. Suitable for US PCS and WCDMA band II applications,
the duplexers exhibit insertion loss of 3.6 dB in the receive band and
2.7 dB in the transmit band with good receive-transmit band isolation
of as high as 57 dB.

VCom Adds Broadband Wireless Technologies
Last-mile access technology supplier VCom, Inc. has completed an
agreement with Wave Wireless Corp. to acquire a cluster of companies
that will provide new broadband wireless technologies, synergistic
sales channels, and substantial revenues in product sales. Under the
terms of the agreement, VCom has purchased WaveRider Communications
(Canada) Inc., WaveRider Communications (USA) Inc., Jetstream Internet
Services Inc., and Avendo Wireless Inc. from their parent WaveRider
Communications Inc, a subsidiary of Wave Wireless Corp. The shares of
all the companies will be purchased for approximately $1 million US
dollars, to be paid in cash. As part of the acquisition, VCom has
entered into a supply agreement with Wave Wireless pursuant to which
VCom will produce under license the 900 MHz product portfolios
marketed by Wave Wireless. The companies also intend to sell each
other's wireless product portfolios. VCom's best-in-class series of
point-to-multipoint products in the 700 MHz, 1.9 GHz, 2.5 GHz, 3.5 GHz
and 5.8 GHz bands as well as its burgeoning WiMAX product line will be
marketed by Wave Wireless to its established customer base.
